2.1.2 Water on Earth's Surface

What causes water at Earth's surface to evaporate into the atmosphere?

• The heat from the Earth's core

• Energy from the Sun

• The gravitational pull of the Moon

• The rotation of the Earth

What happens to water vapor in the air as it cools?

• It dissolves into the atmosphere

• It falls directly back to Earth as rain

• It condenses or crystallizes to form clouds

• It remains as vapor indefinitely

How does precipitation return to Earth's surface?

• As snow, sleet, or hail but only during winter

• Only in the form of rain

• As rain, frozen water falls as snow, sleet, or hail

• Through rivers and streams exclusively

What is the role of gravity in the water cycle?

• It causes the Earth to orbit the Sun, affecting the water cycle

• It pulls water droplets through warm layers of air causing evaporation

• It pulls water droplets down as precipitation

• It has no significant role in the water cycle

What can increase the rate of evaporation in Earth's water cycle?

• Decrease in the amount of moisture in the air

• Lower temperatures in the atmosphere

• Higher temperatures and more moisture in the air

• More intense precipitation conditions

What is the term for the amount of liquid water in something?

• Gravity

• Moisture

• Affect

• Intense

What does the term 'gravity' refer to in the context of scientific vocabulary?

• A process of heating and cooling

• The amount of water vapor in the air

• An attractive force that exists between all objects that have mass

• A change in something due to water

What does the verb 'affect' mean in academic vocabulary?

• To remain unchanged

• To cause a change in something

• To intensify a condition

• To measure the amount of liquid

How is the adjective 'intense' defined in academic vocabulary?

• Mild or weak

• Very strong

• Unchanged or stable

• Attractive or appealing

What are the two main factors driving the water cycle?

• The Sun and the Moon

• Gravity and precipitation

• The Sun and gravity

• Precipitation and evaporation
